Publications at Gazeta de Matemática: here you can see the first page of my papers at the popular science magazine published by the Portuguese Mathematical Society. From 2007 to 2016, the idea was to explain a recent scientific paper related somehow to mathematics to a broad audience - in particular undergrad students in mathematics and related fields and high school teachers. Since 2017, I have more freedom, and I simply speak of whatever I want - but always about mathematics and for more or less the same audience.
If you want to read them in full, you will need a subscription (and be able to read in Portuguese...), or you can e-mail me and ask for a copy.
